You are lucky that yours was on your arm instead of your nose like mine was. They did MOHS surgery on it and cut a lot of skin off. When they got done cutting, it felt like I had been punched in the nose for the next few days. Then I had to have the inside of my nose reconstructed so that I could breathe out of that side of my nose, which was almost as bad as the first surgery. That was Basal cell carcinoma.
I also had Squamous cell carcinoma on my cheek and they cut about a half dollar size slice out of it and stitched it back together. I'm amazed at how well the scar healed.
I have two strikes against me. Having blue eyes and being light complected.
